TypeAPI is a free online tool to generate client SDK code from API specification. Basically, it lets you define your API specification in OpenAPI format and then based on the specification, it generates code for the SDK automatically. This is a very useful tool for people who write and sell REST APIs on RapidAPI like platforms. Now, with this tool, they will not have to write the client SDK code for every programming language manually.
This free website can save your hours if you use it right. There is detailed documentation available that you can go through and see how you can use it to create a valid API specification in JSON format and then get the client SDK code automatically in a click. For generating code, right now it supports the following programming languages.
- Client-Go
- Client-Java
- Client-PHP
- Client-TypeScript
- Markup-Client
- Markup-Html
- Markup-Markdown
- Spec-TypeApi
- Spec-OpenApi
Based on your API specification, it will generate the code in all the above languages. And in the later updates, I hope they add support for other programming languages as well such as Python.
Free tool to Generate Client SDK Code from API Specification: TypeAPI
For now, you don’t even need to sign up or register on the website to use it. You just access this tool from here and then start using it right away. The main interface of the website kind of looks like this.
Now, you start by specifying the API specification in JSON format. There is demo one already that you can use for testing purpose if you want to. Or you can go through the docs and learn the syntax to create a custom API specification.
Finally, when you have entered the valid JSON format, you simply need to click the Generate button. A ZIP file will be downloaded now as you can see in the screenshot below.
Open and extract the ZIP file and inside it, you will find the code for client SDK in various programming languages. You can open any file and go through the code as well if you want to.
In this way, you can now use this simple online tool to generate code from API syntax and specifications. Right now, it only has support for the programming languages that I have already listed. For more sophisticated usage, you can go through the docs and then understand various sections that tells how to define method, payload, and other parameters.
Closing thoughts:
If you are looking for a simple yet effective tool to generate code for REST API endpoints from just their blueprint, then TypeAPI is a very good option. It has the potential to become a standard tool in the future. It is going to save you a lot of time in manually writing the client SDK code for various languages. Just give it API specifications and get the accurate client code that you can distribute anywhere you like.
